The penis, also known as a wiener, is not a muscle. It is made up of spongy tissue that fills with blood when a person gets an erection. The corpus cavernosum, located in the middle of the penis, contains this spongy tissue and arteries. When the muscles around the corpus cavernosum relax, blood flows into the penis, causing it to swell and stiffen. While the penis itself is not a muscle, there are muscles nearby that enable movement and control.

What You'll Learn
The penis is not a muscle
Despite common misconceptions, the penis is not a muscle. While it may be tempting to refer to it as a "love muscle", this term is misleading. The penis is primarily composed of spongy tissue, specifically the corpus cavernosum, which is filled with blood during an erection. This process occurs when the muscles surrounding the corpus cavernosum relax, allowing blood to flow into its open spaces and creating pressure that causes the penis to stiffen and swell.
The penis does not contain any bones, which may come as a surprise to some. In fact, it is possible to break a penis, or more specifically, to cause a penile fracture. This can happen when the penis is twisted hard enough, causing the cylinders that fill with blood during an erection to burst. Such injuries typically occur during certain sexual positions or activities and require immediate medical attention.
The penis is suspended from the pubic symphysis and is surrounded by a bi-layered model of tunica albuginea, which includes fascia, Buck's fascia, dermis, and skin. It is the continuation of the internal root, which is embedded in the pelvis, and extends to the glans. The body of the penis has two surfaces: the dorsal and the ventral or urethral, with the penile raphe running along its ventral surface.
While the penis itself is not a muscle, there are muscles nearby that enable movement and function. For example, the pubococcygeal (PC) muscles play a crucial role in bladder control and sexual function. By performing Kegel exercises, individuals can strengthen these muscles and potentially improve their overall pelvic health and sexual performance.

It is made of spongy tissue and arteries
The penis is not a muscle. It is made of spongy tissue and arteries. The corpus cavernosum contains spongy tissue and arteries that run along the middle of each. When the muscles around the corpus cavernosum relax, blood flows into its open spaces, creating pressure that causes the penis to swell and stiffen. This process leads to an erection, where the spongy tissue fills with blood.
The body or shaft of the penis is located outside the pelvic cavity and is a continuation of its internal root, which is embedded in the pelvis and extends to the glans. It consists of two corpora cavernosa and the corpus spongiosum on the underside. The corpora cavernosa are intimately bound by a dorsally fenestrated septum, which becomes complete before the penile crura.
The penis has a complex structure, with two surfaces: the dorsal and the ventral or urethral. The penile raphe runs along its ventral surface. The body of the penis is surrounded by a bi-layered model of tunica albuginea, a type of fascia. This structure includes other layers such as Buck's fascia, dermis, and skin.
Unlike other mammalian penises, the human penis does not contain a baculum or erectile bone. Instead, it relies solely on blood engorgement to achieve an erect state. This absence of bone is unique among mammals and is believed to have evolved due to changes in mating practices over time.

It has no bone
The penis is not a muscle. It is made up mostly of spongy tissue that fills with blood when a person gets an erection. This tissue is called the corpus cavernosum, and it contains arteries that run along its middle. When the muscles around the corpus cavernosum relax, blood flows into the penis, causing it to swell and stiffen.
While the penis itself is not a muscle, there are muscles nearby that enable movement. These muscles are known as the pubococcygeal (PC) muscles, and they work as a sling to keep the pelvic organs in place. They also play a role in bladder and sexual function. By performing Kegel exercises, individuals can strengthen these muscles, improving their control over their bladder and sexual function.
The penis has no bone, which is a unique feature when compared to other mammalian penises. Instead of relying on a bone, or baculum, to achieve an erection, the human penis fills with blood. This process is made possible by the corpus cavernosum, which becomes engorged with blood, leading to the penis's erect state.
The structure of the penis is quite intricate, with various components working together to facilitate sexual function. The body or shaft of the penis is the external portion that extends from the pelvis to the glans. It consists of two corpora cavernosa and the corpus spongiosum on the underside. These structures are surrounded by a bi-layered model of tunica albuginea, a type of fascia, which provides support and protection.

Penis health and sexual function
While the term "wiener" is colloquially used to refer to the penis, the penis is not a muscle. It is made of spongy tissue that fills with blood during an erection. However, there are muscles nearby that enable movement, such as the pubococcygeal (PC) muscles, which also help control bladder and sexual function.
Penis health is often associated with sexually transmitted infections (STIs) and erectile dysfunction (ED). While these conditions can impact penile health, there are other factors to consider as well. Hygiene practices, lifestyle choices, and underlying health conditions can all influence penis health.
Mental health issues such as anxiety, guilt, depression, low self-esteem, and fear of sexual failure can contribute to erectile difficulties. Sleep deprivation, illicit drug use, and certain medications can also negatively affect sexual function. Additionally, stress and anxiety can impact sexual performance and fertility, while also increasing the risk of cardiovascular disease, which is linked to ED.
Maintaining a healthy weight is crucial as it reduces the chances of diabetes, high cholesterol, and heart disease, all of which can impact penile health. Basic Kegel exercises strengthen the PC muscles, improving bladder control and sexual function.
It is important to pay attention to any abnormal penile discharge or changes in urine colour, as these can indicate health issues such as STIs or kidney and bladder problems, including cancer. Problems with urination, such as difficulty starting or a weak flow, can be signs of an enlarged prostate (benign prostatic hypertrophy, or BPH), which is common in older men.
In summary, penis health and sexual function are influenced by a combination of physical and mental health factors, lifestyle choices, and underlying medical conditions. By addressing these aspects and maintaining a healthy lifestyle, individuals can promote optimal penis health and sexual function.

Penis and pelvic cavity
Despite common misconceptions, the penis is not a muscle. It is made of spongy tissue that fills with blood when a person gets an erection. The corpus cavernosum contains this spongy tissue and arteries that run along its middle. When the muscles around the corpus cavernosum relax, blood flows into the open spaces, causing the penis to swell and stiffen.
The penis is found within the pelvic cavity, which is defined as the middle part of the human body between the lumbar region of the abdomen and the thighs. The pelvis is composed of the bony pelvis, the pelvic cavity, the pelvic floor, and the perineum. The pelvic cavity is further divided into the greater (false) pelvis and the lesser (true) pelvis. The pelvic girdle, or the bony framework of the pelvis, is made up of the two hip bones and the sacrum. The pelvis is held together by the two main joints of the pelvis: the pubic symphysis and the sacroiliac joint. The pelvic floor, which is the inferior muscular layer of the true pelvic cavity, separates the pelvic cavity from the perineum, which lies directly below the pelvic floor.
The pelvic cavity houses several organs and structures, including the urinary bladder, the pelvic colon, internal reproductive organs, and the rectum. The pelvic cavity also contains muscles, arteries, veins, nerves, and pelvic connective tissue. The piriformis is the main muscle that forms the posterolateral walls of the pelvic cavity. It originates from the superior part of the sacrum, passes through the greater sciatic foramen, and attaches to the superior border of the greater trochanter of the femur.
The male pelvis contains the distal parts of the urinary and digestive systems, including the ureter, urinary bladder, urethra, and rectum. The male pelvis also contains the internal genitalia, such as the testes, epididymides, ductus deferens, seminal glands, ejaculatory ducts, prostate, and bulbourethral glands. The urethra extends from the inferior wall of the bladder, penetrates the prostate, and enters the perineum. The perineum, in turn, contains the perineal muscles and external genitalia.
